Page of 4. DESCRIPTION The Viking Quick Response Extra-Large Orifice Upright Sprinkler VK5 is a thermosensitive glass bulb spray sprinkler available in several different finishes and temperature ratings to meet design requirements. The special Polyester, Electroless Nickel PTFE (ENT), and PTFE coatings can be used in decorative applications where colors are desired. In addition, these coatings have been investigated for installation in corrosive atmospheres and are listed/approved as corrosion resistant as indicated in the Approval Charts. (Note: FM Global approves the ENT coating as corrosion resistant. FM Global has no approval classification for PTFE and Polyester coatings as corrosion resistant.) The provides greater flows at lower pressures than standard orifice or large orifice sprinklers. This feature allows reduced pipe sizing for hydraulically calculated sprinkler systems, which require high densities of water. Viking Standard Response Extra-Large Orifice Sprinklers may eliminate the need for a fire pump or reduce the size of the pump if it is required. On existing systems, replacing large orifice sprinklers with sprinklers may provide the higher densities required to allow an increase in the hazard classification of an occupancy. Viking Quick Response Extra-Large Orifice Upright Sprinkler VK5 may be ordered and/or used as an open sprinkler (glass bulb and pip cap assembly removed) on deluge systems.

Page of 4 Ordering Information: (Also refer to the current Viking price list.) Order Quick Response Extra-Large Orifice Upright Sprinkler VK5 by first adding the appropriate suffix for the sprinkler finish and then the appropriate suffix for the temperature rating to the sprinkler base part number. Finish Suffix: Brass = A, Chrome = F, White Polyester = M-/W, Black Polyester = M-/B, ENT = JN Temperature Suffix: 55 F (68 C) = B, 75 F (79 F) = D, 00 F (9 C) = E, 86 F (4 C) = G, OPEN = Z (PTFE only). For example, sprinkler VK5 with a Brass finish and a 55 F (68 C) temperature rating = Part No. 06AB Available Finishes And Temperature Ratings: Refer to Table. Accessories: (Also refer to the Viking website.) Sprinkler Wrenches: A. Standard Wrench: Part No. 058CW/B (available since 98). B. Wrench for coated sprinklers: Part No. 66W/B** (available since 00) **A ½ ratchet is required (not available from Viking). Sprinkler Cabinets: A. Six-head capacity: Part No. 074A (available since 97) B. Twelve-head capacity: Part No. 075A (available since 97) 4. Installation Refer to appropriate NFPA Installation Standards. 5. Operation During fire conditions, when the temperature around the sprinkler reaches its operating temperature, the heat-sensitive liquid in the glass bulb expands, causing the bulb to shatter, releasing the pip cap and sealing spring assembly. Water flowing through the sprinkler orifice strikes the sprinkler deflector, forming a uniform spray pattern to extin- guish or control the fire. 6. inspections, tests and maintenance Refer to NFPA 5 for Inspection, Testing and Maintenance requirements. 7. availability The Viking Quick Response Extra-Large Orifice Upright Sprinkler is available through a network of domestic and international distributors. See The Viking Corporation web site for the closest distributor or contact The Viking Corporation. 8. Guarantee For details of warranty, refer to Viking s current list price schedule or contact Viking directly.

Other limits may apply, depending on fire loading, sprinkler location, and other requirements of the Authority Having Jurisdiction. Refer to specific installation standards. The corrosion-resistant coatings have passed the standard corrosion test required by the approving agencies indicated in the Approval Charts. These tests cannot and do not represent all possible corrosive environments. Prior to installation, verify through the end-user that the coatings are compatible with or suitable for the proposed environment. For automatic sprinklers, the coatings indicated are applied to the exposed exterior surfaces only. Note that the spring is exposed on sprinklers with Polyester, and ENT. For all ENT coated sprinklers, the waterway is coated.
